An important clue to the understanding of Australia is the ecosystem. An ecosystem is a collection of different living and non-living things which are found together and which depend on each other. The sun’s energy is necessary to make the ecosystem work, and, as well, the elements carbon, hydrogen, oxygen, nitrogen, and twelve other elements in smaller amounts, are needed to be continually cycled in the ecosystem.
选项
答案
了解澳大利亚的关键在于它的生态系统。生态系统,就是各种不同的有生命的和无生命的物体汇集在一起并相互依存的集合。太阳能是使这种生态系统运作必需的,碳、氢、氧、氮等元素和少量其他12种元素也需要在这个生态系统中继续循环。
